Abstract

The extracellular potential simultaneous recording permits the investigation of the central nervous activity. The paper presents the design and manufacturing steps of a five electrodes microprobe for recording the electrical activity of neural cells and tissues integrated on the same chip with the electronics. The specific fabrication processes of the integrated microprobe are presented. An implantable neural microprobe is going to be developed to enable the correlation between electrical activity in the human nervous system and externally psychoelectrical stimuli. The electronics accomplish the separation and reduction of the biological noise recording.

用于生物电信号记录的多通道微探针的仿真、设计与微制造
同时记录细胞外电位可以对中枢神经活动进行调查。本文介绍了一种用于记录神经细胞和组织电活动的五电极微探针的设计和制造步骤,该探针与电子元件集成在同一芯片上。介绍了集成微探针的具体制作工艺。一种可植入的神经微探针将被开发出来,以使人类神经系统的电活动与外部精神电刺激之间的关系成为可能。电子器件实现了生物噪声记录的分离和降低。
